Definitions
- the disclosed concept relates to the construction of a housing adapted to be positioned around fans such as attic fans for insulating thereof from the external environment at times when the fan is not being utilized. These designs are useful for preventing the loss of heat through these openings during times of the year and times of the day during which the fan itself is not operating.
- the doors are adapted to open to allow air flow through the insulation device responsive to actuation of the fans.
- Such attic fans are normally installed in a horizontally oriented plane at a central location within the house for allowing warm air to be drawn upwardly therethrough for exhausting outwardly to cool the house especially during periods of warm weather.
- An opening is made in the uppermost ceiling of the upper floor of the house to facilitate this flow of air.
- the apparatus of the present invention is usable to define an enclosure which will define a chamber means therewithin for enclosing and selectively sealing of a fan, such as a large attic or exhaust fan, positioned in the upper areas of the upper floor in the ceilings of many houses.
- a fan such as a large attic or exhaust fan
- Such fans are commonly used in the summer and the present apparatus provides a means for automatically sealing the outlet opening defined for the fan whenever the fan is not in use.
- This enclosure includes a unique double frame configuration including an upper frame and a lower frame each formed as two separate parts which can be detached to allow the apparatus to be collapsible into a compact form to facilitate shipment, movement or other repositioning thereof.
- the upper frame preferably includes two separate upper members engageable with respect to one another.
- Four panels extend vertically in a generally rectangular or square configuration between an upper frame and a similarly configured lower frame.
- the upper frame includes two pivotally movable doors which are biased into the closed position whenever the fan is not operating but which can be moved to the opened position responsive to the flow and movement of air against the planar surfaces of these members.
- Each door is pivotally movable and is a mirror image of one another and includes an axle secured through eyelets to the lower surface thereof.
- the axle is defined to extend through holes defined in the upper frame to facilitate pivotal movement of the doors between the closed position insulating the house and the opened position responsive to actuation of the fan positioned therewithin.
- the axles are preferably suspended by an eyelet pin configuration which is held in place and includes a limit pin extending outwardly therefrom to limit movement of the doors to the opened position. These pins limit the path of movement of the doors away from the closed position toward the opened position by abutting the upper edges of the four panel members. By limiting this movement towards the opened position the doors will be allowed to automatically return to the closed position responsive to cessation of operation of the fan itself.

- the present invention provides an enclosure adapted to extend about a fan 10 which is normally positioned adjacent to environmental structure such as the ceiling of a living area.
- a fan 10 which is normally positioned adjacent to environmental structure such as the ceiling of a living area.
- Such fans are commonly used for exhausting such as when utilized as attic fans 10 and are positioned in the uppermost ceiling in the uppermost floor of a residence or commercial building living area to facilitate exhausting of hot air therefrom particularly during warm seasons. This air movement is further enhanced because such hot air tends to rise.
- the present invention defines an enclosure formed by an upper frame 12 and a lower frame 18 .
- the upper frame 12 and the lower frame 18 are generally each chosen to be generally rectangularly shaped and are spatially positioned with respect to one another to define a fan containment chamber 74 therebetween.
- a plurality of individual insulating panels extend therebetween to preferably form an overall rectangular configuration.
- These insulating panel members include a first insulating panel member 30 , a second insulating panel member 32 , a third insulating panel member 34 and a fourth insulating panel member 38 . These panels extend vertically between the upper frame 12 and the lower frame 18 for defining an overall box-like rectangular or square configuration defining the fan containment chamber 74 therewithin.
- the upper frame 12 preferably includes a first upper frame member 14 and a second upper frame member 16 detachably securable with respect to one another and defining therethrough an air outlet aperture 26 .
- the first upper frame member 14 preferably defines a first upper frame member engagement channel 15 which is capable of receiving portions of the upper edge zone 42 of the insulating panels 30 , 32 , 34 and 38 thereinto to facilitate engagement therewith.
- the second upper frame member 16 defines a second upper frame engagement channel 17 therein which is defined to receive portions of the upper edges of any of the insulating panels 30 , 32 , 34 or 38 extending thereinto for facilitating engagement therewith.
- the lower frame means 18 can preferably include a first lower frame member 19 and a second lower frame member 21 .
- First lower frame member 19 preferably defines a first lower frame member engagement channel 20 defined therein to facilitate engagement with at least a portion of the lower edge zone 44 of the insulating panels 30 , 32 , 34 and 38 to facilitate securement between these panels and the lower frame means 18 .
- the lower frame means 18 including both the first lower frame member 19 and the second lower frame member 21 will preferably include concave engagement channels therein.
- the first lower frame member 19 will preferably be of a concave cross-section and will define a first lower frame engagement channel 20 therein to facilitate engagement with to at least a portion of the lower edge zones 44 of the individual panels 30 , 32 , 34 and 38 .
- the second lower frame member 21 will preferably be of a concave cross-section and will include a second lower frame member engagement channel 22 to facilitate engagement thereof with respect at least a portion of the lower edge zone 44 of the panels 30 , 32 , 34 and 38 .
- the upper frame means 12 is formed by engagement between the first upper frame member 14 and the second upper frame member 16 which can be achieved by engaging the panels with members 14 and 16 when they are placed adjacent to one another.
- Lower locking blocks 67 can be utilized extending into the first lower frame member engagement channel 20 and the second lower frame member engagement channel 22 to facilitate engagement between the first lower frame engagement channel 20 and the second lower frame engagement channel 22 .
- the lower frame means 18 is formed by engagement between the first lower frame member 19 and the second lower frame member 21 .
- engagement between the lower frame members can be achieved by use of locking sleeves 68 which are adapted to extend around the outside of adjacent portions of adjacently positioned frame sections.
- the locking sleeves 68 or the locking blocks 66 and 67 can either be utilized with a set screw 70 such as thumb screws to facilitate securement between each pair of sections of the lower frame.
- the exhaust fan insulated enclosure apparatus of the present invention defines an enclosure with a fan containment chamber 74 therewithin which can be easily sealed whenever the fan is not operating.
- the upper doors will automatically open allowing air to enter the insulated enclosure through the air intake aperture 24 defined within the lower frame 18 and pass inwardly into the air flow conduit 28 or fan containment chamber 74 defined within the four panels 30 , 32 , 34 and 38 .
- the air will then pass further upwardly through the air outlet aperture 26 and be vented upwardly in a standard manner as desired.
- upper door means 46 are included in the apparatus of the present invention.
- This upper door means preferably includes two pivotally doors, namely, namely a first door member 48 and a second door member 50 . Each of these members is defined to extend over approximately half of the upper outlet aperture 26 .
- the first door member 48 is pivotally secured with respect to the first upper frame member 14 such as to normally be positioned extending thereover in a closed position but being operative to move to an opened position extending angularly upwardly responsive to actuation of the fan 10 .
- First door member 48 preferably includes a first pivot axle means 52 mounted adjacent the lower surface thereof to facilitate this pivotal movement between the generally horizontally oriented closed position and the generally upwardly inclined opened position.
- the first pivot axle 52 preferably will extend outwardly on each end beyond the edges of the upper door 46 into first axle holes 60 defined on the interior portion of the first upper frame member 14 . These axle holes or first axle apertures 60 will be loosely mounted with respect to the first pivot axle means 52 such that the panel secured to the aperture can be pivotally movable axially with respect thereto.
- the second door member 50 will be similarly configured such as to include a second pivot axle means 54 to allow the second door member 50 to move between a closed position extending over the second upper frame member 16 and an opened position allowing air flow therethrough.
- the second pivot axle 54 will be pivotally mounted with respect to second axle apertures 61 defined in the inner edges of the second upper frame member 16 .
- a preferred configuration of the present device includes axle holding pins 58 such as eyelet bolts which are positioned to extend through the first door and the second door at locations along the position of securement of the respective axle thereto.
- These axle holding pins 58 preferably include axle holders which have holes defined therein through which the axle extends.
- These axle holding pins 58 can be of various configurations such as the eye bolts 62 shown in FIGS. 7 , 8 and 9 .
- These devices extend through the door and define axial openings corresponding to the axial orientation of the individual axles to facilitate positioning of the axles therewithin and securement of the axles to the respective doors. It should be appreciated that the axle holding pin 58 will usually be configured as eye bolts 62 .
- abutment members or stops can be included secured to the at least one of the axle holding pins 58 or eye bolts 62 on each door 48 and 50 and extending further outwardly therefrom on the side of the door opposite from the axle to provide a stop means for limiting the extent of total movement of the adjacent door toward the opened position.
- the first abutment member or first limit pin 55 limits the total outward movement of the first door member 48 toward the opened position.
- the second abutment member or limit pin 56 limits the total extent of opening movement of the second door member 50 toward the opened position.
- these limit pins 55 and 56 will prevent the doors 48 and 50 , respectively, from moving to an overextended opened position thereby assuring that both doors will return to the generally horizontally oriented closed position after operation of the exhaust fan 10 ceases.
- gravitational forces will urge these doors to fall downwardly to the closed position.
- the doors will automatically be blown to the opened position when the fan starts operating and will fall by gravitational force to the closed position when the fan stops operating.
- this design provides a means for automatically opening and closing the doors in order to insulate the attic fan and adjacent attic fan opening. This automatic means of operation uses very little energy itself and greatly saves energy by preventing heating loss through an attic fan ceiling opening whenever the exhaust fan is not running.
- top frame and the bottom frame can be constructed of any rigid material such as wood, metal or plastic to form the capability of pivotal movement. It is preferable that the frames are formed of a lightweight sheet metal or possibly plastic to facilitate movement and to minimize cost and weight thereof. It is also preferable that the device of the present invention is fully collapsible to facilitate disassembly and storage in very small areas.
- the panels 30 , 32 , 34 and 38 are formed of an insulating material such as styrofoam.
- gaskets or sealing members 72 as shown best in FIGS. 2 and 3 which extend along the upper edges of the first and second door members 48 and 50 to effectively seal therearound to minimize leakage therepast. These gaskets can extend outwardly beyond the edges of the doors to facilitate overlapping engagement and sealing between the doors themselves and between the doors and the upper frame means 12 .
- each door will include several axle holding means 58 preferably in the form of eye bolts extending therethrough and engaging the respective axle for mounting thereof relative to the respective door.
- at least one of the eye bolts utilized on each door will include a mounting sleeve or tube secured to the end thereof to provide the outwardly extending first and second abutment stops 55 and 56 with one mounted on each door. In this manner control of the extent of movement of doors 48 and 50 away from the closed position will be limited to thereby assure that they will both return to the closed position whenever the attic fan ceases operation.
- first door 48 will define a first door outermost edge 76 .
- second door member 50 will define a second door outermost edge 78 .
- Edge 76 will be caused to abut edge 78 responsive to both the first door member 48 and the second door member 50 being positioned in the closed position to further facilitate sealing of air outlet aperture 26 .
